For cast-like stability

The VACOcast (formerly VACOcast Fit) is a fixed-flexion orthopedic fracture boot designed and engineered to help you recover fast—yet be as comfortable as possible during your recovery. Patients rave about their VACOcast!

The modern cast alternative

Traditional serial casting can often be archaic and costly. VACOcast’s patented Vacuum Relief Insert with micro beads, in conjunction with a rigid lattice frame, provides strength and stability that’s as durable as a conventional cast—yet can be removed and re-applied in less than 30-seconds. An optional Safety Seal restricts patients from opening the VACOcast to ensure compliance.

Unmatched versatility with 3-in-1 usability

Secure the limb within seconds

Forms a "Perfect Fit" sturdy cast with no waste

Stability & style allow patients to walk in comfort

Walk sooner

Vacuum orthotics are clinically proven to get people with ankle fractures back to work up to 24 days sooner than traditional fiberglass casts.
